I was talking to the sales rep and he claimed O-200s have never had stuck valve problems and just love 100LL. He then went on to say maybe the O-200A might have had issues, but the B and the C (like he claimed to own and operate more time upside down than right side up!) are fine.

I then walked away trying to keep from laughing.
